The winter 2019 anime adaptation of the Dōkyonin wa Hiza, Tokidoki, Atama no Ue manga is getting a simuldub in North America through Funimation under the name My Roommate is a Cat.
It has Schrödinger’s Cat adding kotringo performing with the song “Unknown World” and is definitely a fun way to get things moving right along with its cuteness.
